What proportion of those surveyed were in favor of tighter enforcement of governmen rules on TV content during hours when children are most likely to be watching when we apply the plus-four method? x + 2 %3D n+4 Using p from the previous step, construct a 95% plus-four confidence interval for the proportion of Americans who are in favor of tighter enforcement of government rules on TV content during hours when children are most likely to be watching. (Round the final answer to four decimal places). P(1-p) CI = p±z* n+ 4 What is the purpose of finding the Plus-Four Confidence Interval for a Proportion?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
The Plus-Four Confidence interval for a proportion is the method used to balance the error originated by using estimates of the population proportion for calculating the standard deviation of the sampling distribution of proportion.
